To all whom it may concern j j Be it known that I, Tnnongm: J. Siwtsm, subject of the Emperor of Austria-Hungary,

and resident of Milwaukel, in the county of Milwaukee and State of Wisconsin, have invented new and useful Improvements in Resilient Wheels, of which the following is a description, reference being bad to the accompanyingdrawings, which are a part of this specification.

The invention relates to resilient wheels.

The invention desi s to provide a resilient wheel of the spring wheel type, having movable wheel members resiliently sup ported.

The invention further designs to provide a wheel of the class described for usoon vehicle wheels or on any other\ wheel or hub for pulleys, drums and the like.

The invention further designs to provide a wheel resilient in a vertical plane for movement of the hub within the wheel in that plane against the action of resilient means disposed in a horizontal plane.

The invention further designs to provide a resilient wheel having two members cooperating with a resilient or spring means, an inwardly projecting portion of the wheel and an outwardly projecting portion of the hub being disposed between "said members so as to provide a cushioning means for the hub and wheel.

The invention further designs to provide a new andimproved form of resilient wheel.

The invention consists in the several features hereinafter set forth and more particularly defined by claims at the conclusion in section. Fig. 2 is a section taken on the line 2-2 of Fig. 1; Fig. 3 is a section taken on the line 3-3 of Fig. 1; Figs. 4, 5 and 6 are detail views of the bearingsand the seats therefor.

The invention is shown as applied to a vehicle wheel comprising an inner movable wheel member 10' having an eperture 11 1 therein for receiving the wheel axle, and an outer movable wheel member 12 which may be connected to the wheel rim by spokes 13.

The means for cushioning the 'movable wheel members is disposed within the outer memberm which forms a casing therefor, the depending flange portion 14 of the onter member being movable within the collar 15 and a flange 16 on the inner mbmber 10, and; a cover 17- is detachably securedto the'outeif member. This construction serves t'ol effieiently house. the resilient means and on elude dust and dirt therefrom, 1

The means for cushioning" the wheel comprises a bearing cup holding member 18 having a flange 19 which is secured to the inner member 10- by any suitable means such as bolts 20, and a bearing cup holding member 21 which is secured by means such as bolts or screws 22 to the interior of the outer mcm ber 12.

The member 18 extends outwardly from the inner member 10 and is rovided with a plurality of bearing cups 2- on either side of the outwardlyproject'in portion, and the, member 21 extends inward 'y' from the outer member 12 and is provided with. bearing cups 24- on either side, similarto those of the'member 18, and these cups are in the inwardly projecting portion of said member.- T'hose portions of the members 18 and 21 f carrying the bearing cups 28 and M aie diswhich register with hearing cups 24011 the same side of the member 21.

A floating ring 28 similar to the ring 25 is disposed opposite to the other side-cf the members 18' and 21, and is provided with hearing cups 29 and 30 which register re-.

spectively with the bearinglcups 23 and 24 on the members 18 and 21 c pee j c t thereto. These two rings 25 and 28 are op-- eratively oonnected together by a plurality of bolts 31, whoseheads 31" are seated in the ring 28 andwhich carry heads 32 secured by nuts 33 at the other ends thereof, so that a spring 34 may be interposed between the mm; 25 and the head 32 of each of the bolts. This plurality of; rings 34 disposed between the heads-82 an the gen 25 will act upon the side'of the ring 25, and will resist any lateral movement ofeither ring 25 or. 28.

The bearing cops in the members 18 and 21 and in the rings Q5 and2t1 which register with them, provide seats for the ball bearings 36 which are disposed betweenthe ring 25 and 28 and the members 18 and 21.

drawings, Fig. 6 shows a bearing seat which is designed for a light load, Fig. 5 one which is designed for a medium load, and Fig. 4 one designed for a heavy load,the continu- 1 ation of the lower curved portion being more or less abrupt as the use of the device may require.

The bolts 31, as previously pointed out, serve to connect the rings 25 .and 28, and the springs 34 acting against one face of the ring 25 serve to hold both rings in position adjacent the respective sides of the members 18 and 21, and also to hold the bearings 35 disposed therebetween.

The operation of the device is as follows: Any vertical movement of the outer or inner wheel members 12 and 10 Withrespect to each other, will cause a like movement of the members 21 and 1.8 which are connected to them respectively, which will move the ball bearings 35 causing them to ascend or descend in the seats 23 and 29, 23 and 26, 24 and 27, 24 and 30. This will result in the exertion of an outward force against the sides of the rings 25 and 18, which force will be counteracted by an opposite force exerted by the springs 34. Thus it follows that for every vertical movement of the inner and outer movable wheel members with respect to each other, there will be a corresponding. vertical movement of the rings 25 and 28, and an outward movement causing the exertion of a force in a horizontal plane, which force will be counteracted -by an opposite force exerted by the springs 34 in that plane. It also follows that each of the rings 25 and 28 will move as a unit, and that each of the springs 34 will takean' equal proportion of the load exerted by said rings. In the use of the device on traction wheels, it will be apparent that'it will be necessary to provide springs 34 of a strength sufiicient to oVercome and exceed the tra'lctive force applied to the wheels. 7

The invention thus exemplifies a resilient wheel in which vertical movement of the movable members of the wheel is resisted and counteracted by the horizontal movement of the cushion means. 4

The invention is not to be restricted to the details of construction hereinset forth, but may be varied so as to be within the scope of theappended claims. l r

What I claim as my invention is: 1. In a resilient wheel, the combination of a plurality of movable wheel members, each of said members having bearing cup holding members secured thereto, floating bearing cupiholding rings disposed on either side of said bearing cup holding members, a plurality of bearings in the cups formed by said cup holding members and rings, and means for resiliently securing said bearings within the cups comprising means secured to one of said rings, a plurality of springs mounted on said last named means respectively and operatively'connected to the other of said rings.

2. In a resilient wheel, the combination of a pair of movable wheel members, a bearing cup holding member secured to each of said members, a ring on either side of said bearing cup holding members having bearing cups registering with the bearings cups in said members, bearings disposed in the cups formed by said rings and said cup holding members, a plurality-of bolts secured-to one of said rings, and a plurality of springs mounted on said bolts respectively and operatively connected to the other of said rings, said springs being disposed in a plane opposite to .the plane of movement of said movable wheel members and acting uni;v formly on said rings to resist outward move ment thereof.

3. A resilient wheel comprising movable wheel members, a plurality of floating rings between said members, a plurality of bolts secured to one of said rings, a plurality of springs mounted on said bolts respectively and bearing against the other ring, and means on both of said movable members and said rings for permitting the ringsto move outwardly against the action of said springs.

4.- A resilient wheel comprising movable wheel members, a plurality of floating rings between said members, spring-securing means secured to one of'said rings, a plural ity of springs mounted on said securing means respectively and bearing against the other ring, and means on both of said movable members and said rings for permitting the rings to move outwardly against the action of said springs.

5. A resilient wheel comprising movable wheel members, a plurality of floating rings between said members, springsecuring means fixedly secured to one of said rings and slidabl mounted in the other ring,a plurality-o springs mounted on said securing means respectively and bearing againstsaid other ring, and means on both of said movable members and said rings for permitting the rings to move outwardly against the action of'said springs.

In testimony whereof, I afiix my signature, in presence of two witnesses.
